Programing the Quadzilla XZT+

Recommended Posts

I decided to try the XZT+2000 tune in my new XZT+... I'm thinking the low speed trailer towing will want the agressive bottom end tune. What a PITA. Neither of my XP computers had the .net 3.5 network needed. The Quadzilla instructions are confusing, though all there. It took a nervous hour with both my desktop open to the instructions and (on the second try) the programing done on my laptop. I suppose one could print out the instructions... but you really need them. I think (hope) I got it done. Hopefully additional tuning wil not be so difficult.Russ

The truck has been running good as I get ready to go camping. I topped the tank today... hand calc running empty is 17.5... lie-o-meter is 17.1 right now. I am running the IAT Foolern (143*) after 1 minute warm up... I've not had a chance to make up the multi-position switch & install it before this trip). This is not bad for this 4.10 geared truck. I have the XZT+ loaded with the 2000 tune but have been running it on the +15 hp setting as I'm empty & don't need the power. I can feel the modest improvement can easier pull a grade without down shifting & accidentally chirping the tires on a launch to get out into traffic. I'm liking this choice. When I hook up, I'll go to the power setting & see how it pulls under load.
